405275 ÷ 77 
Our goal is to divide 405275 by 77.

Moving on to step 1:
77 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 77

Moving on to step 2:
If we divide 40 by 77, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 77

On to step 3:
The number 77 fits into 405 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 385 from 405, we get 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 77

Let's proceed to step 4:
If we divide 202 by 77, we get 2 and a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we subtract 154 from 202, we get 48.
Grab the next digit (7) from the dividend, add it to 48, then carry on: 487 / 77

Going ahead to step 5:
When dividing 487 by 77, we get 6 with a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 526.0
The remainder is 25 after subtracting 462 from 487.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 77

Step 6:
When dividing 255 by 77, we get 3 with a remainder of 24.
The next digit of our result is 3. 
Result so far: 5263.0
Deduct 231 from 255 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
The number 77 fits into 240 3 times, leaving a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 5263.3
Subtract 231 from 240 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 8:
If we divide 90 by 77, we get 1 and a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 5263.31
The remainder is 13 after subtracting 77 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
130 divided by 77 is 1 with a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 5263.311
Subtract 77 from 130 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Our division results in 5263.311 with a remaining 0.0053.
